Africa: New model shows future impact of circumcision on HIV epidemic probably underestimated

Projections of the impact of circumcision on the HIV epidemic in sub-Saharan Africa based on clinical trials may underestimate the number of infections that can be averted by around 40 per cent, according to an international group of epidemiological modellers. The findings, published in advance online by the journal Sexually Transmitted Infections, come from new epidemiological modelling work that incorporates findings from a pooled analysis of two recent studies that evaluated the impact of circumcision on HIV transmission from men to women.
